Review on Amrxuts 234-9066 Upstream Air Fuel Ratio O2 Oxygen Sensor (2004-2008 TSX 2.4L) by Marcus Rash

This solved my CEL code P0135 (O2 Sensor Heater Circuit Bank 1 Sensor 1) on my 2005 Acura TSX. It was a direct correspondence to the old part. When I pulled the old sensor out, part of the heater circuit was open causing my CEL to light up as soon as the engine started, even after the codes were cleared. The CEL didn't come back after about 50 miles and I was able to pass the local emissions tests (after driving the car enough to complete the OBDII readiness tests).
